(01. 24-2055) This invention relatesto a separable-fastener, .2 I I M l I more particularly toth'eslidefor operating fas- :will-extend through the cut away port1ons and engage the outer' ends of the fasteners to force the mer er this type.

" Sliders for'separablefas'teners may move along the separable fasteners due to strains placed on the separable fasteners after separated on through other causes and it is desirable to look a slider on the separable fasteners in some position along the stringers on which the fasteners are positioned. Various means of applying pressure on one or the other of the fasteners or by use of a projection extending between the fasteners have been attempted. Usually these constructions are expensive to produce and require precision formation.

One of the objects of this invention is to provide a simple and inexpensive lock for a slider to prevent the slider from movement along the fasteners.

Another object of this invention is to provide a lock for applying pressure in such a direction that a firm support is provided and considerable pressure may be applied in order to frictionally lock the slider in position.

More specifically an object of the invention is to apply pressure on the sliders forcing the slid-- ers toward each other when in locked position and at the same time locking the slider.

Another object of the invention is to release this locking means when the pull tab is lifted for actuation of the slider along the fasteners.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a top plan view of separable fasteners and a slider positioned thereon of the construction of this invention;

Fig. 2 is a sectional View on line 22 of Fig. 1 on an enlarged scale with the bottom plate omitted;

Fig. 3 is a perspective view of the pull tab showing the locking means as provided thereon; and

Fig. 4 is a perspective view of the slider with the pull tab detached.

In proceeding with this invention I have modifled the slider for separable fasteners by cutting away a portion to permit the locking means carried by the pull tab to extend through the cut-away portion of the slider to engage the separable fasteners for holding the same in locked position. I have cut away one of the plates of the slider adjacentits edges and provide spaced fingers on the pull tab so that when the tab is maeea m posmdn to serene] the sliders the fingers fasteners toward each other into firm engaging position and thus by reason of this frictional grip on the fasteners the slider will not move along the fasteners.

With reference to the drawings, Ill designates one part and II another part of some garment or material which it is desired shall be separably connected together. A stringer I2 is sewed onto the part In and a stringer l3 sewed onto part II. Each of these have clamped upon them, separable fasteners l4 with interlocking ends l5 so as to inter-engage as at I6 shown in Fig. 1.

A slider designated generally l1 and shown in perspective in Fig. 4 consists of a pair of plates, the top plate being designated l8 and the bottom plate designated l9, which plates are held together through means of a post or neck 30 which serves as a separator and guide for the fasteners M to move them from looking position. This slider is flared outwardly at its upper end as at 20 so as to accommodate the separated portions of the fasteners after the slide has been moved along them. Flanges 2| and 22 are provided on these plates for the guiding of the fasteners through the slider.

A pull tab 25 is hingedly attached to the slider I1, such for instance as by means of raised stock 26 of the plate Hi to receive portions of the pull tab 25 in the eye so raised therefrom.

The pull tab 25 is provided with a pair of fingers 21 of a longitudinal extent greater than the similar dimension of the fasteners as shown in Fig. 1, and so located that they will pass through cut outs 28 in the flanges and top plate of the slider H so that as this pull tab 25 is swung downwardly on its hinge 26 the fingers 21 will move through the recesses 28 and engage the ends of the fasteners H (see Fig. 2) and these fingers 21 will be of such distance apart that as they engage the ends of the fasteners the fingers will spread slightly so that their inherent tendency to return to their normal position will force the fasteners toward each other and as this engagement is at a location where they are locked one with the other the fingers will apply a considerable amount of friction on the fasteners and will hold the slider firmly in position.

The fingers on the pull tab will be in looking position when the pull tab is as shown in Fig. 1 located against the slider and parallel to the fasteners, while when this pull tab is swung outwardly about its hinge .26 the fingers will be lifted sitely disposed fingers on said tab spaced a dis-- tance less than the overall distance between the ends of said fasteners when interlocked and wider than the space between two adjacent interlocking fasteners to yieldingly engage the ends of said opposed fasteners when the tab is in looking positiOn and exert a binding effect.

2. A slider as set forth in claim 1 wherein said plate upon which said tab is hinged is notched at its outer edges to expose the ends of said fasteners at a location through which said fingers move.

3. A slider as set forth in claim 1 wherein said plate upon which said tab is hinged is notched at its outer edges to expose the ends of said fasteners adjacent the hinge connection and said fingers are adjacent the hinge connection.

4. A slider as set forth in claim 1 wherein said fingers are of a longitudinal extent greater than one of said fasteners.
